Sorry about weird writing of cubed squareroots, unsure how to write cubed square roots and square roots.

2b SQRT^3(16b^2) + SQRT^3(128b^5)
---------------------------------------------
Do you mean 2b(cube root of 16b^2) + (cube root of 128b^5)
-----
If so you get:
2b(2*cbrt(2b^2)) + 4b*cbrt(2b^2)
---
(4b + 4b)*cbrt(2b^2)
---
8b*cbrt(2b^2)
==========================
Cheers,
